Carbo Culture

What Carbo Culture does

Carbo Culture is a Finland-based biochar technology and project developer (parent entity Carbo Culture Oy) that operates a proprietary pyrolysis platform called Carbolysis™ to convert waste biomass into stable biochar for permanent carbon sequestration, biogenic syngas for renewable energy, and high-purity biocarbon (Biographite®) for industrial applications. The company runs a co-location model building reactors at or near partner industrial sites — including the R&D R2 reactor in Escalon, California (2022), the R3 prototype in Kerava, Finland (3kt CO2/a, 2023), and the planned ARC Middenmeer commercial facility in North Holland targeting 20,000+ tCO2e annual net sequestration — to integrate with energy, feedstock, and offtake infrastructure on the customer side.

The company monetizes across four primary revenue streams: (1) Biochar Carbon Removal (BCR) credits certified by Puro.earth and now eligible under the EU CRCF BCR methodology, sold under multi-year offtake agreements to corporate buyers including Rothschild & Co and Zendesk; (2) physical biochar sold into horticulture, growing media, and landscaping markets, anchored by Dutch greenhouse operators such as Royal Pride and the ECW Energy cluster; (3) renewable electricity and heat from syngas combustion supplied to co-located industrial hosts; and (4) Biographite® biocarbon (>90% fixed carbon) sold to steelmakers including SSAB and Ovako as a fossil-coke replacement for electric arc furnaces, and as a conductive additive for carbon-negative concrete in construction. Customers are exclusively enterprise-scale industrial counterparties, engaged via direct field sales and long-term technical-commercial partnerships.

The business is venture-backed (True Ventures, Cherry Ventures, Alumni Ventures, GenZero, Tesi, KIMPA among others) with cumulative capital of approximately $31.5M+ across equity and non-dilutive grants (EU EIC, German SPRIND, Dutch RVO). Leadership includes CEO and co-founder Henrietta Moon, COO Sten Stoltze (ex-Ørsted CTO), CTO Bjørn Dahlen (ex-GE/Ørsted), and a board with representation from investors and independent directors. The company is in pre-commercial scaling phase, with R3 pilot as the largest operating asset and ARC Middenmeer positioned as the first full-scale commercial deployment, targeting 200kt CO2/a across the C10+ facility pipeline by 2029+.

Core offering

Carbo Culture is a project developer operating proprietary Carbolysis™ pyrolysis reactors that convert waste biomass into high-purity biochar (>90% carbon content) for permanent carbon sequestration, while co-generating tar-free biogenic syngas that is used to produce renewable electricity and heat. The company sells certified biochar carbon removal credits (Puro.earth), supplies biochar to greenhouse horticulture and agribusiness markets, and produces Biographite® biocarbon for metallurgical (green steel) and conductive concrete applications.

Product overview

Carbo Culture operates as a project developer with proprietary climate technology built around its patented Carbolysis™ platform. The core technology converts waste biomass into stable biochar (permanently sequestering carbon for thousands of years) while generating renewable energy. The product portfolio consists of: (1) Carbolysis™ as the core technology platform, (2) Biochar Carbon Removal (BCR) Credits - the company's primary carbon removal product certified by Puro.earth, (3) BCR Biochar - sold into agribusiness for horticulture and landscaping applications, (4) Renewable Energy - electricity and heat from biogenic syngas, and (5) Biocarbon (Biographite®) - high-carbon material for metallurgy and construction including conductive concrete. The flagship ARC Middenmeer facility represents the first commercial-scale deployment of the technology.
